MDT brief
Discussion questions (2, 1 blocking)
BLOCKING OQ-CD20-CONFIRMATION
Is CD20+ status confirmed by histology (IHC)? Without CD20+, rituximab/obinutuzumab are not indicated.
Anti-CD20 therapy is the backbone of most lines of treatment; absence of CD20 expression fully changes the regimen.
→ pathologist
OQ-STAGING-COMPLETE
Has complete staging been done (Lugano + PET/CT or CT)?
Prognosis and track selection depend on stage and tumor burden.
→ radiologist

Missing data for doctor action
| Priority | Clinical item | Owner | Why it matters | Next action | Blocks |
|---|
| CRITICAL | CD20 IHC status cd20_ihc_status
| pathologist | Confirms CD20-directed therapy is biologically appropriate. | Verify CD20 IHC result, specimen, method, and report date. | - |
| CRITICAL | Lugano stage lugano_stage
| radiologist | Defines lymphoma extent and supports tumor-burden and response-assessment decisions. | Document Lugano stage from PET/CT or contrast CT staging. | - |
| RECOMMENDED | LDH ratio to ULN ldh_ratio_to_uln
| medical_oncologist | Supports prognostic scoring and aggressive-biology flags. | Enter LDH with local upper limit of normal. | RF-AGGRESSIVE-HISTOLOGY-TRANSFORMATION |
| RECOMMENDED | FIB-4 liver fibrosis index fib4_index
| infectious_disease_hepatology | Screens hepatic fibrosis risk before hepatotoxic therapy or antiviral coordination. | Calculate FIB-4 from age, AST, ALT, and platelet count. | - |
| RECOMMENDED | PET/CT date pet_ct_date
| radiologist | Shows whether baseline staging is recent enough for treatment planning and later response comparison. | Document baseline PET/CT date or explain alternative staging modality. | - |
